Surprisingly there is not a function to get a top-level US timezone. We can get a valid timezone from Intl object, but it is not a top-level, i.e., US/New-York vs US/Easten. Get a top group of US timezone is usually, for it will simplify the timezone selection dropdown. In this article, I will show how to create custom functions using raw IANA data to achieve this goal.
